Gear motor activating a motor vehicle functional member

Abstract

A geared motor is used control the movement of a vehicle member, such as a window. A reducer casing is arranged at one end of the motor and includes a sensor assembly for detecting the speed and direction of rotation of the motor. The sensor assembly includes a coded magnetic wheel and Hall effect cells that arc positioned between the wheel and a member for concentrating magnetic flux. The Hall effect cells are placed opposite from a lateral face of the wheel and are spaced apart from one another. Output from the cells is sent to a processor to determine the speed and direction of rotation of the motor.
